This tape measure shows the time of day in inches

Arduino TeamMay 1st, 2020

Tape measures are great for determining length, width, and height. But what about the fourth dimension, time? Normally you’ll need a different device to show this ever-changing entity, but creators Alex Fiel and Anna Lynton have managed to turn the measuring tool into a clock.

Instead of being pulled to a certain distance, the tape extends automatically representing the hour by number of inches shown.

Unrolling is controlled by a NEMA 17 motor inside its custom 3D-printed housing, along with an Arduino Nano and RTC module for proper timekeeping.
